the K3's mic gain, compression, and power level have been carefully set up on
each band for contest use.

oscillator frequency in Hz. Typically it will be 49380.000 +/- 1000 Hz.

(Advanced) OPTIONAL SPURIOUS SIGNAL REMOVAL: Can be used to
remove fast-tuning receiver "birdies" that are audible even with an antenna
connected. (An alternative in SSB mode is to turn on auto-notch.)
Limitations: Applies only to CW/SSB/DATA modes, and only to the main
receiver. In CW and DATA modes, SIG RMV should not be used in combination
with a CONFIG:PB CTRL setting of
STEPS: (1) Select the desired band (for transverter bands, use the I.F.), as well
as the desired mode. (2) Adjust the DSP controls (SHIFT/WIDTH or LO/HI
CUT) to the settings you use most often. (3) Locate a birdie to be removed. A
birdie is "fast-tuning" if a small change in the SHIFT control (e.g. 50 Hz) moves
the birdie about 400 Hz or more (with a narrow filter selected, this small shift
may move it completely out of the passband). Such birdies result from UHF
harmonics of the VFO. If you test a birdie using SHIFT, be sure to return SHIFT
to its original setting before continuing, because SHIFT affects the birdie
frequency. (4) Change the SIG RMV parameter to
about the birdie, including VFO frequency, mode, bandwidth, and SHIFT value.
(5) Try different parameter values, starting with
removed (shifted out of the audible passband). Each time you change the
parameter, exit the menu and see if the birdie has disappeared. (Each SIG RMV
entry applies to a single 100-Hz VFO segment, e.g. from 28135.30 to 28135.39,
so you'll have to tune slowly through that 100-Hz range using 10-Hz steps to
make sure the birdie has been completely removed.) You may hear a slight tuning
artifact as you tune in and out of the affected VFO segment. (6) Repeat steps 3
through 5 for the adjacent 100-Hz VFO segments if required to completely
remove the birdie. (7) Repeat steps 2 through 6 for different DSP control settings
you use in the present mode. Note: If you change your CW sidetone pitch, you
may need to re-do the procedure for signals removed in CW mode.
